Reg Kit Watch Creative has extended its MuVo line of USB Flash key drive-cum-MP3 players with the MuVo TX.

The new model brings the memory capacity up to 256MB, and speeds song transfers thanks to a USB 2.0 connector.

Like its predecessors, the TX operates as a USB Mass Storage device, so tracks can be loaded using a variety of operating systems just by dragging them onto the mounted device's icon.

Mac OS X users may care to check out Chuck Bennett's little app, MuVo Helper, which integrates the player with iTunes and clears out all the extra files Finder adds for its own benefit but which confuse the player. You can get MuvoHelper here.

Windows users wanting an alternative MuVo experience could do worse than download Notmad Explorer from Red Chair Software, which provides rather better track management than you can get simply by copying files over.

Powered by a single AAA battery, the TX offers up to 15 hours' playback time, assuming you're using an alkaline cell and only playing 128Mbps MP3 files. The compact unit weighs just 43g with a battery in place. The TX has a voice record function to the player. Up to 16 hours' worth of mono messages can be taped.
